| `MANIFEST_DIR` | `__manifest` | manifest layout |
| Commit graph dirs (retired) | `_graph_commits.lance` / `_graph_commit_actors.lance` | retired in Phase B; lineage lives in `__manifest` (`graph_commit` / `graph_head` rows) since RFC-013 Phase 7. A graph this binary creates has neither. |
| Recovery audit dir | `_graph_commit_recoveries.lance` | one row per crash-recovery action (`omnigraph commit list --filter actor=omnigraph:recovery`) |
